So a few months ago, right after the release, i got the collector's edition of Starcraft II. in there was a USB drive with on it the complete version of starcraft 1. the installer was an automated program that automatically entered the CD key. NO OTHER DOCUMENTATION WAS INCLUDED!
so i just installed it, and wanted to register the game to my battle.net account. however, i need the game key for that. where can i find that? i've already checked the text files that were on the drive and in the installation folder, but i can't seem to find it.
